[Lex Computer & Tech Group/LCTG] Computer graphics question

[Schonfeld]

I want to measure how new-track starting locations are distributed around
the decay source.  Quantum mechanics makes a clear prediction but,
remarkably, it has never been tested (to my knowledge).  Times or frame
numbers are nice-to-have.  I could do without them.
